ème molaire (P = 0,008 ; OR = 2,5). Les dents causales des cellulites sous-mylohyoïdiennes étaient les 2 èmes et les 3 èmes molaires mandibulaires. Ces résultats concordent avec les données de la littérature. Cependant, chaque forme topographique doit être en nombre statistiquement significatif pour étudier au mieux les relations avec les dents causales. Abstract -Perimaxillary cellulitis: etiology and anatomo-clinical relations.We retrospectively studied maxillofacial space infections presenting to oral and maxillofacial surgery unit (Aristide Le Dantec teaching hospital) over a 47-month period. Odontogenic causes, dental sources of infection and anatomic maxillofacial spaces associated were evaluated and compared with other recent statistics. 349 patients were admitted. The origin of maxillofacial space infections was predominantly odontogenic (92.7%). The most common cause of odontogenic infections was decay (79.9%). At the maxillary, 1st and 2nd molars were the main source of buccal maxillary space infections (34%). At the mandible, 1st and 3rd molars were respectively the predominant source of buccal mandibular (41.2%) and submandibular (44.8%) space infections. Buccal mandibular space infections were related to 1st and 2nd molars (P = 0.008 ; OR = 2.5). Only 2nd and 3rd molars were the dental sources of submandibular space infections.  Etiologic aspects in this series were in agreement with the medical literature. Maxillofacial spaces infections seem related to dental sources of infection.

Introduction: The proximity of the roots of the posterior maxillary teeth to the maxillary sinus is a constant challenge to the dental practitioner. Because the majority of studies have assessed the relationship regarding molars, the present study focused on premolars. Methods: Cone-beam computed tomographic images of 192 patients were reconstructed in sagittal, coronal, and axial planes to quantify the distances between the root apices of the maxillary premolars and the adjacent maxillary sinus. Measurements were taken for each root, and data were correlated with age, sex, side, and presence of both or absence of 1 of the 2 premolars. Results: A total of 296 teeth (177 first and 119 second premolars) were evaluated. The mean distances from buccal roots of the first premolars to the border of the maxillary sinus in the sagittal, coronal, and axial planes ranged from 5.15 AE 2.99 to 8.28 AE 6.27 mm. From palatal roots, the mean distances ranged from 4.20 AE 3.69 to 7.17 AE 6.14 mm. The mean distances of second premolars were markedly shorter in buccal roots between 2.32 AE 2.19 and 3.28 AE 3.17 mm and in palatal roots between 2.68 AE 3.58 and 3.80 AE 3.71 mm, respectively. The frequency of a premolar root protrusion into the maxillary sinus was very low in first premolars (0%-7.2%) but higher in second premolars (2.5%-13.6%). Sex, age, side, and presence/absence of premolars failed to significantly influence the mean distances between premolar roots and the maxillary sinus. Conclusions: Based on the calculated mean distances of the present study, only few premolars (and if so second premolars) would present a risk of violating the border of the maxillary sinus during conventional or surgical endodontic treatment or in case of tooth extraction.

“…In contrast, it has been shown in surveys, that up to 95% of dentists refer their patients solely for an OPG scan before implant placement with only a relatively small number of referrals for a CT scan [10,11]. It is interesting to know, that several studies assessed the vertical and horizontal relationship between the tooth root apex and the inferior wall of the maxillary sinus using CT diagnostic method [12][13][14][15][16]. It was concluded that CT is more accurate than OPG in assessing the tooth root and sinus relationship [17].…”

Objectives:The purpose of the present study was to investigate the reliability of both periapical radiographs and orthopantomograms for exact detection of tooth root protrusion in the maxillary sinus by correlating the results with cone beam computed tomography. Material and methods: A database of 1400 patients scanned with cone beam computed tomography (CBCT) was searched for matching periapical (PA) radiographs and orthopantogram (OPG) images of maxillary premolars and molars. Matching OPG images datasets of 101 patients with 628 teeth and PA radiographs datasets of 93 patients with 359 teeth were identified. Four observers assessed the relationship between the apex of tooth root and the maxillary sinus per tooth on PA radiographs, OPG and CBCT images using the following classification: root tip is in the sinus (class 1), root tip is against the sinus wall (class 2) and root tip is not in the sinus (class 3). Results: Overall correlation between OPG and CBCT images scores was 50%, 26% and 56.1% for class 1, class 2 and class 3, respectively (Cohen's kappa [weighted] = 0.1). Overall correlation between PA radiographs and CBCT images was 75.8%, 15.8% and 56.9% for class 1, class 2 and class 3, respectively (Cohen's kappa [weighted] = 0.24). In both the OPG images and the PA radiographs datasets, class 1 correlation was most frequently observed with the first and second molars. Conclusions:The results demonstrated that both periapical radiographs and orthopantomograms are not reliable in determination of exact relationship between the apex of tooth root and the maxillary sinus floor. Periapical radiography is slightly more reliable than orthopantomography in determining this relationship.
